k.rennerandClaude Fable 5	384bd54e8b	edge-host: E3onCAN service — read the E380 meter directly Passive listener (no bus writes, coexists with the single open3e instance) decoding the E380's own CANopen broadcasts: per-phase active/ reactive power, currents + cosPhi, voltages + grid frequency, and the meter's cumulated import/export counters — instead of trusting the VX3's relayed values. Pinned to V0.5.2; ~5 Hz broadcasts throttled to one MQTT update per DID per 10 s; JSON payloads under the open3e/ prefix with the shared broker user.

edge-host: E3onCAN service — read the E380 meter directly

Passive listener (no bus writes, coexists with the single open3e
instance) decoding the E380's own CANopen broadcasts: per-phase active/
reactive power, currents + cosPhi, voltages + grid frequency, and the
meter's cumulated import/export counters — instead of trusting the
VX3's relayed values. Pinned to V0.5.2; ~5 Hz broadcasts throttled to
one MQTT update per DID per 10 s; JSON payloads under the open3e/
prefix with the shared broker user.
